| Outline of Final Research Achievements |
The largest reason to decide long-term outcome after the lung transplantation is chronic rejection. The chronic rejection after the lung transplantation is diagnosed as existence of bronchiolitis obliterans (BO), pathologically. However, the formation mechanism, suppression method, and the treatment are still unknown.
We previously revealed that IL-6 affected the BO formation. As for the IL-6 receptor, the signal transmission is made by STAT3. We hypothesized that we could control the BO formation by restraint by activation of STAT3. After searching for the inhibitor using mouse BO model, it was suggested that the BO formation was reduced by the zinc administration. However, the mechanism of the inhibition was still unknown. We continue this study of the mechanism elucidation.
